The Sony Xperia M is a good looking Android smartphone, with a streamlined user interface. Its specs include a 4.0 inch touch display, 4GB of internal storage which can be expanded through microSD, a 5 megapixel camera capable of 720p HD video capture, a secondary camera for video calls and is powered by a 1GHz dual-core processor with 1GB of RAM.Unfortunately its price $200 - $250 price feels a little more than the device is worth at times. Especially with some affordable competitors like the Nokia Lumia 520 winning over potential Sony customers.
